AIDetectPlus is an advanced AI content detection and humanization tool designed to help users identify AI-generated text in essays, papers, blogs, social media posts, and more. It works with major models like ChatGPT, Gemini, Claude, and GPT variants, providing high-accuracy detection (claimed up to 97%) along with detailed explanations of where and how AI patterns appear. Beyond detection, AIDetectPlus includes a powerful humanizer that rewrites AI text to make it sound more natural and bypass other detectors, plus features like plagiarism checking and specialized modes for students, educators, and marketers.
Is AIDetectPlus Free or Paid?
AIDetectPlus uses a credit-based freemium model. Basic features such as AI detection, plagiarism checks, and limited access to AI chat or PDF interactions are available for free (with new users often getting initial free credits, e.g., around 1,000 words). Full access to advanced humanization, unlimited usage, higher word counts, API integration, and premium tools requires purchasing credits or opting for enterprise plans. Credits are a one-time purchase and never expire, offering flexibility without recurring subscriptions for most users.
